# Entry types
## Description:
The entry types are split into two categories: geometries for labels and form-elements for classifications. Currently there are 8 types of classification entries.
## Geometries:
Geometries have optional color attribute. In addition geometries of the root level can also have a shortcut attribute. You may choose number-keys from 0-9 as shortcuts to speed up the labeling process.
In addition there are 10 colors to choose from.
{% hint style="warning" %}
Shortcuts must be unique per label configuration.
{% endhint %}
### Available geometries:
* 
Polygon: Consists of at least 3 points, points can be added and moved after initial drawing
* 
Bounding Box: The bounding box can be moved and resized after initial drawing
* 
Line: Consists of at least 2 points, points can be moved
* 
Point: A single point that can be moved
* Image segmentation: Consists of at least 3 points, cannot be selected or moved after initial drawing but can interact with other segmentations.
{% hint style="info" %}
In addition if you configured at least one Image segmentation , **Data**Gym.ai will add an eraser to remove segments. You cannot choose this tool within the label configuration.
{% endhint %}
## Classifications:
Classification-entries consist of a question and options for the chosen type of form. Classifications can be marked as required.
{% hint style="info" %}
Required fields will prevent the user from getting the next task while labeling if not filled out.
{% endhint %}
### Available classifications:
* 
Checkbox: Has at least 1 answer option
* 
Option: Has at least 2 answer options, only one may be selected
* 
Textfield: Has a max length attribute (default is 256 characters)
